Seasons are periods of the year with distinct weather conditions and day lengths.
The four seasons — winter, spring, summer, autumn — can vary significantly in characteristics and can prompt changes in the world around them. Here, we explore these four seasons in more detail.
Attributes of the seasons may vary by location, but there are still broad definitions that cross most of the boundaries.
In the spring, seeds take root and vegetation begins to grow. The weather is warmer and often wetter. Animals wake or return from warmer climates, often with newborns. Melting snow from the previous season, along with increased rainfall, can cause flooding along waterways, according to the Federal Emergency Management Agency (opens in new tab) (FEMA).
In the summer, temperatures may increase to the hottest of the year. If they spike too high, heat waves or droughts may cause trouble for people, animals, and plants. For example, in the summer of 2003, the high temperatures claimed more than 30,000 lives, according to Encyclopedia Britannica (opens in new tab). Rainfall may increase in some areas, as well. Others may receive less water, and forest fires may become more frequent.
In the autumn, or fall, temperatures cool again. Plants may begin to grow dormant. Animals might prepare themselves for the upcoming cold weather, storing food or traveling to warmer regions.
Various cultures have celebrated bountiful harvests with annual festivals. Thanksgiving is a good example. "Thanksgiving in the United States is a historical commemoration but it has a spiritual dimension strongly associated with homecoming and giving praise for what has been bestowed upon us," Cristina De Rossi, an anthropologist at Barnet and Southgate College in London, told Live Science.
Winter often brings a chill. Some areas may experience snow or ice, while others see only cold rain. Animals find ways to warm themselves and may have changed their appearance to adapt. "In a similar way to the Autumnal theme, Winter festivals celebrate the return of the light during a time of deepest physical darkness," said De Rossi. The Indian festival of Diwali, for example, which takes place between October and November, celebrates the triumph of righteousness, and light over darkness.
Seasons are not the same everywhere
The timing and characteristics of the seasons depend upon the location on Earth. Regions near the equator experience fairly constant temperatures throughout the year, with balmy winters barely discernible from warm summers. This is because it gets fairly constant light from the sun, due to its position on the outer curve of the Earth, according to the Atmospheric Radiation Measurement (ARM) program.
For areas to the north and south, the seasons can change more significantly. People closer to the poles might experience icier, more frigid winters, while those closer to the equator might suffer hotter summers.
Meteorological season dates: Northern Hemisphere
According to Time and Date:
– Spring: March 1 to May 31;
– Summer: June 1 to August 31;
– Autumn (Fall): September 1 to November 30
– Winter: December 1 to February 28 (February 29 in a leap year).
Other factors can also affect the weather and temperature over the seasons; some areas experience dry summers as temperatures spike, while others might call summer their "wet season." A wet season is when a majority of a country or region's annual precipitation occurs, according to the Met Office. Mountainous regions might experience more snowfall than plains within the same latitude, while oceanfront property could see an increase in violent tropical storms as the weather shifts.
The time of year a region experiences a season depends on whether it is in the northern or southern hemisphere. The Southern Hemisphere experiences winter while its northern neighbors encounter summer; the north sees the slow blossom of spring while the south brings in the autumn harvest.
What causes the seasons?
(opens in new tab)
The cycle of seasons is caused by Earth's tilt toward the sun. The planet rotates around an (invisible) axis. At different times during the year, the northern or southern axis is closer to the sun. During these times, the hemisphere tipped toward the star experiences summer, while the hemisphere tilted away from the sun experiences winter, according to the National Oceanic and Atmospheric Administration (NOAA) (opens in new tab).
At other locations in Earth's annual journey, the axis is not tilted toward or away from the sun. During these times of the year, the hemispheres experience spring and autumn.
The astronomical definition of the seasons relates to specific points in Earth's trip around the sun. The summer and winter solstice, the longest and shortest day of the year, occurs when Earth's axis is either closest or farthest from the sun. The summer solstice in the Northern Hemisphere occurs around June 21, the same day as the winter solstice in the Southern Hemisphere, according to NOAA. The south's summer solstice occurs around December 21, the winter solstice for the north. In both hemispheres, the summer solstice marks the first day of astronomical summer, while the winter solstice is considered the first day of astronomical winter.
Equinoxes are another significant day during Earth's journey around the sun. On these days, the planet's axis is pointed parallel to the sun, rather than toward or away from it. Day and night during the equinoxes are supposed to be close to equal. The spring, or vernal, equinox for the northern hemisphere takes place around March 20, the same day as the south's autumnal equinox. The vernal equinox in the southern hemisphere occurs around September 20, when people in the north celebrate the autumnal equinox. The vernal equinox marks the first day of astronomical spring for a hemisphere, while the autumnal equinox ushers in the first day of fall.

But changes in the weather often precede these significant points. The meteorological seasons focus on these changes, fitting the seasons to the three months that best usher them in. December to February marks meteorological winter in the Northern Hemisphere and meteorological summer in the southern. March, April, and May are lauded as spring or autumn, depending on the location, while June through August are the months of summer for the north and winter for the south. September, October, and November conclude the cycle, ushering in fall in northern regions and spring in southern, according to NOAA.
The seasons can bring a wide variety to the year for those locations that experience them in full. The weather in each one may allow people to engage in activities that they cannot perform in others — skiing in the winter, swimming in the summer. Each season brings with it its own potential dangers, but also its own particular brand of beauty.

The Short Answer:
Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.
The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons. When the earth's axis points towards the sun, it is summer for that hemisphere. When the earth's axis points away, winter can be expected.
spring runs from March 1 to May 31; summer runs from June 1 to August 31; fall (autumn) runs from September 1 to November 30; and. winter runs from December 1 to February 28 (February 29 in a leap year).
Spring begins with the Vernal Equinox, Tuesday, March 19, 2024, 11:06 p.m. Summer begins with the Summer Solstice, Thursday, June 20, 2024, 4:51 p.m. Fall begins with the Autumnal Equinox, Sunday, September 22, 2024, 8:44 a.m. Winter begins with the Winter Solstice, Saturday, December 21, 2024, 4:21 a.m.
Seasons change due to the change in the position of the earth around the sun. Was this answer helpful?
The Earth rotates on its own axis and it is tilted at an angle of 23.5° with respect to its orbital plane; this causes the occurrence of seasons. The revolution of the Earth around the Sun, which requires 365 days and 6 hours, in an elliptical orbit also causes the change in seasons.
The four seasons—spring, summer, fall, and winter—follow one another regularly. Each has its own light, temperature, and weather patterns that repeat yearly. In the Northern Hemisphere, winter generally begins on December 21 or 22.
Remind students that the two reasons seasons occur are the tilt of a planet's axis and its orbit around the sun.
Climate, weather and the change of the seasons affect much of what we do each day. Many people choose where to live based on the climate. Weather can be both a helpful and destructive force for people and their property. The change of seasons allows for many different types of work, food, celebrations and recreation.
The four seasons: spring, summer, autumn (fall) and winter.
Geographically speaking, when all the countries that lie in the northern hemisphere (above equator) are experiencing summer right now. This means all the countries located in the southern hemisphere must be experiencing winter. The Southern Hemisphere is the half of the Earth south of the Equator.
Fall: Starts on March 20 or 21, and ends on June 20 or 21. Winter: Begins on June 20 or 21, and lasts until September 22 or 23. Spring: Goes from September 22 or 23 until December 21 or 22. Summer: Starts on December 21 or 22, and lasts until March 20 or 21.
In spring, the weather begins to get warmer and trees and other plants grow new leaves. Summer is the hottest season and has long, usually sunny, days. In the fall, the weather becomes mild and leaves start falling from many types of trees. Winter is the coldest season, with short days.

The Earth's annual trip around the sun forms the basis for the astronomical calendar in which seasons are defined by two solstices and two equinoxes. The Earth is tilted 23.5 degrees on its axis of rotation, and how the North Pole is oriented toward or away from the sun determines two of these astronomical dates.
Scientists think an Earth without a tilt would be stratified into climate bands that would get progressively colder as you moved away from the equator. Humans would never survive the continuous winter of the high latitudes, and so we would likely congregate in the planet's tropical midsection.
The seasons are caused as the Earth, tilted on its axis, travels in a loop around the Sun each year. Summer happens in the hemisphere tilted towards the Sun, and winter happens in the hemisphere tilted away from the Sun. Was this answer helpful?
Seasons are caused because of the Earth's changing relationship to the sun. The Earth's travels around the Sun, called an orbit, once a year or every 365 days. As the Earth orbits the Sun, the amount of Sunlight each location on the planet gets every day changes slightly. This change causes the seasons.
The Earth orbits the sun once every 365 days and rotates about its axis once every 24 hours. Day and night are due to the Earth rotating on its axis, not its orbiting around the sun. The term 'one day' is determined by the time the Earth takes to rotate once on its axis and includes both day time and night time.
Answer: Seasons result from the yearly orbit of the Earth around the Sun and the tilt of the Earth's rotational axis relative to the plane of the orbit. Seasons occur because the earth is tilted with respect to the sun. ... At the same time, the South Pole has tilted away from the sun so it is winter there.
Four personal seasons of life
Because just as nature, so do we experience different seasons in our personal life. These different seasons can be likened to life, winter, spring, summer, and fall.
While the exact definition of a season's timing and length can differ in different areas based on local conditions, in most of the Northern Hemisphere meteorological summer is generally defined as the three months of June, July and August, with the season starting on June 1 and ending on August 31.
“Summer” came from the Old English name for the season “sumor”, which in turn came from the Proto-Germanic *sumur-, which itself came from the Proto-Indo-European root *sam-, meaning summer. *sam- seems to be a variant of the Proto-Indo-European *sem- meaning “together / one”.
But did you know that we actually have two different types of seasons? There are Astronomical Seasons, and Meteorological Seasons.
season changes on earth due to revolution of earth around the sun and due the tilted axis. Explanation: If the seasons didn't changed this will result in the axis being not tilted. This will result in extremely cold climate near the poles and extremely hot climate near the equator.
There is actual scientific evidence that humans are more likely to get less happy during the fall and winter season. According to a study on human behavior based on seasons, humans are more likely to suffer from seasonal affective disorder, or SAD starting during late fall and early winter.
Unfortunately, the changing of the seasons can have even more serious repercussions than dry skin and weight gain. For example, seasonal affective disorder, or SAD, can cause major depressive episodes, usually beginning in late fall or early winter.
Autumn is a feminine given name derived from the Latin word autumnus, meaning "fall" or "autumn". The personification of Autumn from an 1871 Currier and Ives print.
|Spring||Feburary to March||Sunny and pleasant.|
|Summer||April to June||Hot|
|Monsoon||July to Mid-September||Wet, hot and humid|
|Autumn||September end to November||Pleasant|
You can never get bored on a summer day or night. During the day, there are fun activities such as: swimming, sports, picnics, and barbeques. Friends and family spend a lot of time together during the summer time. There is a lot of good food, drinks, and fun music.
Why Are There Seasons? - YouTube
The combination of the revolution around the Sun and the fixed angle of the Earth's axis result in the seasonal changes: temperature changes, angle of sunlight, and the number of daylight hours.
What causes the seasons to change? The Earth's tilt in relation to the Sun.
The axis of rotation of the Earth is not perpendicular to the plane of its orbit. It is this tilt in its axis of rotation while it revolves around the sun that is responsible for the change of seasons on the Earth.

☀ De vier perioden van een jaar - lente, zomer, herfst en winter - hebben verschillende kenmerken en verschillen per locatie.
Andere factoren kunnen ook het weer en de temperatuur gedurende de seizoenen beïnvloeden; sommige gebieden ervaren droge zomers wanneer de temperatuur stijgt, terwijl anderen de zomer hun "natte seizoen" kunnen noemen.. Het zuidelijk halfrond ervaart de winter terwijl de noordelijke buren de zomer in kaart brengen; het noorden ziet de langzame bloesem van de lente terwijl het zuiden de herfstoogst brengt.. De cyclus van seizoenen wordt veroorzaakt door de aarding van de aarde in de richting van de zon.. Tijdens deze tijden kantelde het halfrond naar de ster die de zomer ervaart, terwijl de halfrond weggekanteld van de zon de winter doormaakt, volgens de National Oceanic and Atmospheric Administration (NOAA).. Op andere locaties in de jaarlijkse reis van de aarde staat de as niet schuin in de richting van of van de zon af.. De zomer- en winterzonnewende, de langste en kortste dag van het jaar, vindt plaats wanneer de as van de aarde het dichtst bij of het verst van de zon is.. Op beide hemisferen markeert de zomerzonnewende de eerste dag van de astronomische zomer, terwijl de winterzonnewende wordt beschouwd als de eerste dag van de astronomische winter.. De lente, of lente-equinox voor het noordelijk halfrond vindt plaats rond 20 maart, dezelfde dag als de herfstnachtevening in het zuiden.De lente-equinox op het zuidelijk halfrond vindt plaats rond 20 september, wanneer mensen in het noorden de herfstnachtevening vieren.. De lente-equinox markeert de eerste dag van de astronomische lente voor een halfrond, terwijl de herfstnachtevening luidt op de eerste dag van de herfst.. Maart, april en mei worden geprezen als lente of herfst, afhankelijk van de locatie, terwijl juni tot augustus de zomermaanden zijn voor het noorden en de winter voor het zuiden.. September, oktober en november sluiten de cyclus af, luiden de val in de noordelijke regio's en de lente in het zuiden in, volgens de NOAA.
Man was made for seasons, and seasons for man. This is true of all kinds of seasons, but the crackling clarity of Fall has brought it once again to mind. The changing of the seasons reminds us of the passing of our lives. The Seasons of Nature The most universal of the seasons are the seasons of the year. In each there is both a mood and an invitation to reflection which has been part of the wisdom of man from the beginning. Every age and every culture recognizes the new birth of
The Seasons of Nature. It ought to lead us to wonder whether God does not somehow create and orchestrate the seasons of our lives as He does the seasons of the year.. But at the end of that argument, we should not be surprised to find that God has also a supernatural set of seasons which He uses to translate the wisdom of the natural seasons into a language of purpose for our lives.. Lent provides this time of training, an intense effort to be somehow ready for the full impact of the growing Revelation.. Now we know not only how to live each season of life but why; and not only our purpose but also our destiny..
